BoilerFaultCodesYour boiler is taking a temporary, normal breather to prevent the burner from turning on and off too quickly, which helps save energy and protect the components.
This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.
Technical description: Remaining burner anti-cycling time in min
What causes this fault?
This occurs when your boiler reaches its target temperature too quickly and needs to pause before firing up again. It is a protective measure designed to prevent 'short-cycling,' which stops the internal components from wearing out prematurely due to constant starting and stopping. The pause gives the water in your radiators time to cool down slightly so the boiler can run for a more efficient, longer period next time.
This status is more common during autumn and spring when the weather is mild and your home requires less heat than the boiler’s minimum output.
